Clinical Trial Summary

Regeneration of periodontal tissues is the primary goal of periodontal surgery regenerative procedures. Most techniques include an incision of the interdental papilla associated with defect. That may impair the volume and integrity of interdental tissues. Azzi et al. proposed a novel technique (Entire Papilla Preservation Technique, EPPT) for bone regeneration to secure the integrity of interdental papillae. This study will search for differences in regeneration therapy of isolated interdental intrabony between Modified Entire Papilla Preservation Technique (MEPPT) alone and combined with EMD, demineralised freeze- dried bone allograft and sCTG. Moreover the aim of this study was to evaluate the clinical applicability and one- year outcomes in the regenerative treatment of isolated deep intrabony defects.


Clinical Trial Description

Regeneration of periodontal tissues is the primary goal of periodontal surgery regenerative procedures. Both resorbable and nonresorbable barrier membranes have been widely used to receive periodontal regeneration, as well as different types of biomaterial have been investigated. Enamel matrix derivative (EMD, Emdogain, Straumann) become popular for periodontal regeneration, especially that membrane exposure due to bacterial contamination may deteriorate periodontal regeneration and wound healing especially in the interproximal areas. Hence different surgical procedures have been proposed to preserve interdental papilla. Most techniques include an incision of the interdental papilla associated with defect. That may impair the volume and integrity of interdental tissues. Azzi et al. proposed a novel technique (Entire Papilla Preservation Technique, EPPT) for bone regeneration to secure the integrity of interdental papillae by providing a tunnel- like undermining incision. The completely preserved papillae improve wound healing process, stabilize the blood clot and the volume of interdental tissue. EMD and bone substitutes (allograft) are applied in the defect to promote periodontal regeneration. By using subepithelial connective tissue graft (sCTG) better quality (thickness) of soft tissue can be achieved. This clinical report describes surgical approach using modified papilla preservation technique for regenerative periodontal therapy. This study will search for differences in regeneration therapy of isolated interdental intrabony between Modified Entire Papilla Preservation Technique (MEPPT) alone and combined with EMD, demineralised freeze- dried bone allograft and sCTG. Moreover the aim of this study was to evaluate the clinical applicability and one- year outcomes in the regenerative treatment of isolated deep intrabony defects. ;
